A few questions on this one: - How much CPU and RAM resource do you need/intend to provide to each Oracle DB? - What version of Oracle? - Do you plan to use ASM and Grid Infrastructure? I specialize in virtualizing Oracle Databases (among other things). Given the choices of virtualization platforms you gave, I would tend to go with either VirtualBox or KVM, in that order of preference. However, if I may, you will be much better off handling these things from a performance point of view using a bare metal hypervisor, and in that case, I would recommend the free version of ESXi. It will give you superior capability and performance, and allow you to do things that you would otherwise not be able to. For example, You could take the 4 Gig-E NICs, combine them into a single virtual switch, and then connect all of the database VMs to it such that they would automatically share the bandwidth. You could even create separate port groups on different VLANs to keep the networking traffic separate and assign different databases to different VLANs. That's just barely scratching the surface of things on the networking side alone as well. I'm happy to discuss specifics further if you like. I am a Linux guy and major Fedora fan, and I also am a VCAP-DCA and VCAP-DCD. I do this on my job every day. I also will be a panelist at VMworld 2011 later this month on a discussion about virtualizing Oracle databases (Session BCA1548). If anyone else is coming, definitely drop me a line!
